Application filed October 3, 1887..'

I olare that the following is a full, clear, and

complete description thereof. The said improvements relate to the peculiar construction and arrangement of the parts `composing the door or section of a stove, I whereby the mica or isinglass connected withv the door or otherfpart of a coal stove or furnace is prevented from being'smoked over or blackened by the 'deposition of carbon from the coal upon the mica. g Y

It is wellknown that mica as generally used in stoves, especially those in which is burned bituminousy coal, soon becomes so lblackened over by the smoke that lthe pleasant sight of the fire is obscured7 giving a dirtyand untidy appearance to the stove. It is the purpose of these improvements to so construct the door k or section of a stove or furnace having connected mica therewith as to prevent its being blackened by the smoke from the burning fuel of oil, gas, coal, vapor, Sto.

For a more full Aand complete description of thesaid invention' reference will be made to the following specification, and to the drawings annexed and 'forming a part thereof.

Figure 1 is a front view of the door. Fig. 2 is a transverse section in the line .fr xof Fig. 1. Fig.3 is a sectional rear or backy view of the door.

,Like letters of reference refer to likeparts in the drawings and specification.

The door referred to consists of three sec- 4o tions or parts, A B C, excepting the mica, D,

which form ltwo panels, as shown in Fig. l. The door may, however, be so arranged in its parts as to have one, two, or more mica panels. The general contour of the door shown lseen in- Fig. 2.

dotted lines a, Figi.) Betweenv this frame and the back side-of they door are placed the panel or'panels of mica, D D,`as` showninFigs; 2 and 3, which mica .is of such size as not' to' im-pinge upon or-lap over the openings E in theframe'B It is designed thatftheseV open.

ingsA in the frontsectionframe or section,B,. shall be in open relation with eachother, as

0n the outside (of the frameB iss'ecu'red the conduit, G, which extendsaround on the undersides thereof, as indicated in.y Figs. 2 and 3, and over the slots or openings E and'F, before mentioned. l

By means of the screw-bolt and gnut H the parts of the door r'eferredto are fastened together, with the'micainterposed between'the frame B and theback of therdoorsection C, with the section A secured upon the frame ;B.-

Inthis way the mica D and frame 'B are held between the back side of the section'G and the Vsection A, as seen in'Fig. 2.

the frame B is the edge or rim J, Fig. 2, which holds the said frame and mica panels in place vsection A, provided with an air passage or f' v yto the back of the dor-se'ctionO, in connection with the screwrbolt, as before stated: By this construction and arrangement of the several parts theonlyoutlet from the air-conduit" .G is through the narrow-opening orlopenings I, which extend entirely around thepanels of mica. l e v By means of one ormoreopenings or slots, E F,`in the sections G and frame B-"the air passes from the exterior through the ysaid' slots into the air-conduits G, then out through" the slit or opening I over the inside faces `of the tion of the fuel, as indicated' by the `arrows in Figs 2 and 3. As the currents'of air pass in vand through' the said slots or openings into the interior of the stove, they extend overthe sur! face of the mica, and are brought intimately in contact with the smoke from the fuel', which produces a combustion of kthe inflammable gases and smoke, consuming them or reducing the carbon of the smoke into carbonio-acid gas or other colorless gas, which will not darken or smut over the mica. It may beconsidered that it is due to currents of fresh air constantly passing in and over the face ofthe mica that the smoke is prevented from coming into contact with the mica. In practical operation it is found that an ignition of combustible gases from the fuel takes place on the admission of air from the exterior through the said passages and openings in the door; hence currents of air from various points are admitted from the outside and interposed between the mica and smoke from the fuel, which prevents the mica from being blackened.

The described door may be hinged to the stove or furnace in the usual way or be otherwise connected therewith in a suitable manner.

nace secured together by suitable means, the A door-section C, a frame, B, with the mica interposed between said frame and the back of section C, in combination with the section A, having an air-conduit arranged in open relation with apertures in said frame B and section C, with an outlet from the conduit, whereby the external air is induced and directed over the interior face of the mica, in the manner and by the means substantially as described.

2. A stovedoor provided with one or more mica panels and having air openings or conduits in the sections of said door leading from the front thereof to the inside of the' mica, constructed and` arranged for the induction of external air through said openings or conduits and directed to and over the interior face ot' the mica, in the manner substantially as described, and by the means for the purpose set forth.

In testimony whereof I aiiix my signature in presence of two witnesses.
